CAN-CLOSING MACHINE.

To; (ill "lo/m it may concern Be it known that I, I)ANIEL P. ROBINSON,

Baltimore, in the State of Maryland, have invented certain new anduseful Improven'ients inCan-Ulosing lt'laohines, of which the. followingis a description, reference being had to the accompanying drawing, andto the letters and figures of reference marked thereon.

The invention relates to new and useful improvements in can closingmachines, and

' more especially to this type of machine for cover permanently securedto the securing a cover to a-filled can by a rolled doubleseam. i

An object of the invention is to provide means for removing a coi'erfrom a. stack holder, which means also operates to place the cover onthe filled can ibody and clench said cover to the can body, whereby itis securely held thereon, so thatl the covered can may be taken to theclosing head and the can body.

A furtherobject of the invention is to provide means for placing a.cover on. a can body, which operates in conjunction with a doubleseaming mechanism, and is so disposed relative to the double seamingmechanism, as to place the cover on the can-body and clench the. same tothe can body, prior to its being conveyed to theseaming head, of theclosing machine.

These and other objects will in part be obvious, and will in part behereinafter llmleffillly described.

9 is an end view of a can body, showing the jcover applied and clenchedthereto. citizen of the United States, residing at .to a can closingmachine consisting of a The invention is herein shown as appliedsupporting frame l, on which is mounted a seaming head 2, carryingseaming rolls 8. This seaming head is rotated and operated froma shaft4, which is moved up and down by a lever5, and the shaft 4 is rotatedthrough a gear connection. 6, from a shaft 7, in the head of the frame.The

lever 5 is raised and lowered from a cam disk 8, which is mounted on across shaft 9 geared to the shaft 7. The can bodies orfilled cans arefed underneath the seaming head by a drum feed 10. Said drum feed 10consists of a support on which the filled can bodies rest, and alongwhich they may Said can bodies are moved along the support .by a drum1'], which is formed with a spiral thread 12. This thread is wound onthe drum in' such a manner as, to move the filled cans first beneath thecover supplying and clenching station 13,- and ing station, suflicientlylong for the cover 'to be applied and clenched thereto, after which thespiral thread again moves the filled cans to the seaming stat1on,-whereit remains at rest during theseaming opera-v tion. a

The drum 11 is driven by a shaft 14, which is geared to the shaft 9 inthe frame of the .machine. The cover supplying means consists of asupportingplate 15. This supporting plate is mounted above the drumfeed. and is held properly positioned relative thereto oy'a dependingslide 16, (see Fig. which is secured to the plate and is formed with a Thead running in suitable grooves and guiding standards 17 molded to theframe of the support for the Feeding drlun. By' this construction, the'supporting plate is allowed t move .verti- The spiral rally relative tothe drum feeding. mee'hmovesupportmg plate 15 is raised and lowered by alink 18, whichis pivoted at its lower,

ends to an ear 19, formed on the upper face the link of the supportingplate 15. Said link 18 at its upper end, is pivotally'connected toalever20, which is mounted on the shaft carrying the lever of the seamingmechanism. This lever 20 will therefore, move in unison with the lever5, and the cover support and applying means Will therefore, move up anddown in unison With the seam- 7 ing head.

Mounted on the support 15, is a stack holder for the covers, whichas'herein shown, consists of three supportmg'rods 21.

These supporting rods 21, may be carried by arms 22, adjustably attachedto the plate 15, so that by swinging the arm 22, the distance betweenthe supporting rods may be varied and therefore, the size of the stackholder changed to accommodate different size covers for can ends. Anaperture 23 is formed in the supporting plate 15, and the can covers inthe stack holder pass through said aperture to the lower face of thesupporting plate. This aperture 23 will be made of sutlicient size toaccommodate 7 the largest can cover on which the machine is adapted tooperate, and ifdesired, the rods 21 forming the stack holder, may extendthrough the arms 22 to the lower face of the plate, in which case, theplate would be slotted as at 24, to allow the adjustment of the arms. i

At the lower face of the supporting plate 15, I have provided receivingand applying screws 25. As herein shown, I have provided three screws25, equally spaced about the aperture in the supporting plate 15. Thesescrews have their threads formed a suflicien't distance apart to receivethe preliminary curled edge of a cover. These screws'project underneaththe stack holder so that the covers in the stack holder will rest on theupper faces of the three screws. Upon the rotating of these screws, thelower cover in the stack holder will be separated from the remainingcovers in the stack holder, and carried downwardly by the screws. Ateach rotation of the screws a cover will be taken from the stack holder,and therefore, several covers will be supported and'carried down by thescrews, one after another. This screw feeding means for removing a coverfrom a stack holder,

' forms no part of the present invention per se,

butis shown and described in the patent to Edwin Norton, No. 968,493,granted August. 23rd, 1910. The movement of the suppru'ting plate 15, asabove noted, is, so

timed that the drum of the feeding" mechanism will position the can bodyunderneath the plate, and while said can body is held stationaryunderneath said plate, the supporting plate 15 is moved downward throughthe swinging of the lever 20, and

connection 18, and therefore, the

cover will be positively carried down on to .the can body. It oftenoccursvin closing filled cans, that certain of the fruit will float inthe syrup, and therefore, extend above the top of the can. By theconstruction wherein the cover applying means is vraised and lowered,said filled,cans with floating fruit therein, may be moved underneaththe cover-applying means, and as the head or supporting plate '15 movesdownwardly with the cover positively carried thereby, the fruit will becrowded down into the can body and the cover crowded into the mouth 'ofthe can body, and firmly seated therein. It often occurs also, that canbodies'are slightly out of true and therefore, when a can cover isseated in the can body, if it be released before it is po.-:-:i'- tivelyjoined to the can body by a seam, that the spring of the can body willthrow ed the. cover. The present invention ill? efore, contemplates notonly the placingof the cover forcibly on the filled cans, but.

also the clenching of the cover to the'can body so that it is positivelyheld thereon until it is brought to the seaming mecha nism, where'it ispermanently attached to the can body.

The clenching, mechanism, as herein shown, is a part of the screws whichdeliver and place the can cover on the can body. As clearly shown inFigs. 6 and 7, L

have formed a radial slot 26 in the lower face of each screw, and insaid slot is placed a hardened steel plate 27, which is formed with aprojecting lip 28. .This' projecting lip extends slightly beyond thebody of the screw, that is, the base of the threads of the. screw,and'is formed with a groove 29 in the outer face thereof. Said plateprojects a, less distance at its forward end than at its rearward end.This plate as the screw rotates, will be brought into contact with thecurled edge of the cover, and will force the same at the point ofcontact with the cover, beneath the projecting flange on the can body,as'clearly shown in Figs. 6 and 9.

As each screw is provided with a clenching member. the cover will beclenched to the can'body in three places-30, 31, and 32, as clearlyshown in- Fig. 9. This clenching of the can body positively holds thecover on the can body. 'The screw thread at the bottom of the screw,vanishes at the point 33, and as soon as the curling lip 28 is freedfrom the cover by the rotation of the screw,- said screw will beentirely released froin the cover so that the supporting plate 15,tog-ether with the screws and the stack holder, may be raised from thecan body having the cover attached thereto, and said other, fordifferent size covers.

the drum feed, and carried to the seaming head, where the curled edge ofthe cover and flange of the can body are finally rolled into a doubleseam.

Instead of providing the screw withva separate'plate forforminga-curling lip, I may form thecurling lip integral with the screw. asshown at 34 in Fig. 8, but .asthe separate plate construction is muchmore easily manufactured, 'Iprefer to use the construction shown in Fig.7.

The screws are rotated simultaneously by a chain 35, which chain engagesa pinion 36 carried by a short shaft on which each screw is mounted. Theshort shaft for the screws, as herein shown, is mounted in a bearing 37,which is attached to an arm 38 secured -to the supporting plate 15. Saidplate may be slotted swung about their connections so as to vary theposition of the screws relative to each The slack in the chain is takenup by an idler 39. The shaft for one of the screwsfilG is positively'rotated from the' shaft 9 of the seaming mechanism,

through a shaft 40 which has a universal connection 41 with the shaft 9,and a universal connection 42 with a sleeve 43, telescoping the shaftcarrying the screw. Said sleeve 43 is splined to the shaft of the.screw, so that said screw will be positively rotated from the shaft ofthe seaming machine, but said screw may be moved vertically relative toits operating mechanism.

This allows the supporting plate carrying the screws and the covers tomove up and down as above noted, and the screws to rotate continuously.At each side of the sup-.

porting plate are downwardly projecting flan es 44, which flangesterminate short of the support for the drum feed when the supportingplate 15is in its lowered position. The .flangesai are merely extendedalong the sides of the plate 15, and do not interfere with the feedingof a can body underneath the supporting plate, and from beneath thesupporting plate -to the seaming head. The can body is positioned under-1 neath the stack holder by a guiding flange til) 45, and the thread onthe drum.

In order to assist in rounding up the can bodies which may beconsiderably distorted, a ring 46 is secured to the depending flanges44, at a 1point beneath the screws 25. This ring is ormcd with a taperedopening so .that as the supporting plate 15 is lowered, the taperedopening will receive the can bodyhnd round up the same to a certainextent, so thatthe-cover may be forcibly seated in said can body. Theopening through the ring 46, is of course, sufficiently large to allowthe flange on the can body to readily pass therethrough, and also toallow the can body with the cover clenched thereand said arms may be.on, to pass through the ring. Boththe upper and lower edges areslightly tapered to prevent said ring from looking with the can body orwith the cover.

In the operation of the device, cans are placed on the support and, the

the fill d spiral thread on the drum moves the cans along the supportunderneath the cover applying and securing means. At this point,

the drum is-so shaped that the the thread in can body is given a dwell.The supporting plate carrying the stack of can covers, will move downover the filled cans, and the ring carried thereby will round .up thefilled can to-reeeive the cover. been carried down by the scre ws,-which of course, are operated in proper timing with the other parts ofthe machine, will be forcibly pushed down on to the can body, crowdingthe fruit floating therein into the can body, and firmly seat the coverin the can body, after which the clenching lips carried by each screwwill turn the curl oithe cover underneath the flange on the can body atthe points where the cover is supported by the screw. As soon as theclenching occurs, the cover is released from thcscrew, and thesupporting plate with the stack holder and screws is raised from thefilled can with The cover which. has

the coverattached, and the ring is also lifted above the filled. can,after which the thread on the drum will again pick up the can and moveit along to the seaming head. WVhile the seaming action occurs on onecan,

another can is having the cover applied thereto and clenched.

It is obviousthat minor changes in the details of construction, and. thearrange. ment of parts may be made, without departing from the spirit ofthe invention setforth in the appended. claims.v It is also obvious thatinstead of using drum feeds as herein shown, anysuit'able feedingmechanism maybe used for presenting the filled cans to the cover placingand clenching mechanism, and to the head seaming mechanism.
